Plug in each point into the inequality:
5x - y > 4
A. (4,2)
5x - y > 4
5(4) - 2 > 4
20 - 2 > 4
18 > 4 This is a solution because 18 is greater than 4
B. (5, -2)
5x - y > 4
5(5) - (-2) > 4
25 + 2 > 4
27 > 4 This is a solution because 27 is greater than 4
C. (0, -1)
5x - y > 4
5(0) - (-1) > 4
1 > 4 This is not a solution because 1 is not greater than 4
D. (-3,1)
5x - y > 4
5(-3) - 1 > 4
-15 - 1 > 4
-16 > 4 This is not a solution because -16 is not greater than 4
E. (2,7)
5x - y > 4
5(2) - 7 > 4
10 - 7 > 4
3 > 4 This is not a solution because 3 is not greater than 4
F. (8,4)
5x - y > 4
5(8) - 4 > 4
40 - 4 > 4
36 > 4 This is a solution because 36 is greater than 4
A, B, F are solutions to the inequality
